The stoichiometric ratios for the reactants in the balanced chemical equation should generate the most heat and produce the maximum temperature change. This temperature change will be proportional to the amount of reaction that occurs. Using the method of continuous variations and graphical analysis allows us to find the mole ratio for solutions that we do not know the identity of. Hypothesis: My hypothesis is that we can find the mole ratio of two reactants by measuring the change of temperature during the reaction. From my understanding of stoichiometry, I learned that the mole ratio in a balanced equation should consume the greatest amount of reactants. For this particular experiment, I hypothesized that the ratio of the greatest temperature change produced should be the balanced ratio. Materials:
